Innovation is wonderful, but it’s hard to believe this has enough users to flush out the challenging bugs. Maybe if it had some kind of correctness proof, but it just seems like there are way too many subtle bugs in file systems in general for me to try a new FS.

Building out test infrastructure for correctness to support the project sounds like a fantastic idea.

That said, while it's compatible with Linux via fuse, unless you're helping to build RedoxOS, I don't think there's any real expectation that you would try it.
